Main Dashboard showing across Buddypress on ALL user Dashboards!

I have no idea why or what happened, or if I did something to make this happen. I went to edit a user dashboard and noticed that it looked identical to my dashboard on the main site including scheduled posts, comments, stats, etc. I checked around and every blog dashboard I visited is the same! Also, I am not able to add categories to individual blogs, etc. because it wants me to choose a category from the main site list, but then when you choose one it just shows up on the blog as Uncategorized (as tho none were selected.)

This is the first time I’ve heard about this kind of behavior on a default installation even in subdomain structure. Deactivate all plugins including BuddyPress, mu-plugins and bp-custom.php as well if you have them and change theme to default twentyten theme. Clear cache. See if same behavior persists.
